Last fall I received an email from a thoughtful,
successful high school teacher whose students I would be happy
to have in my class. The gist of his communication was
the question I raise in the title of this editorial.
My correspondent teaches a second-year high
school course for which he has three objectives: (1) deal with
standard topics not included in the first-year course for
lack of time; (2) introduce organic and biochemistry;
and (3) develop problem-solving abilities by getting the
students to work in groups on "real-world" problems. He has made
a conscious decision not to teach an
advanced-placement course--a decision with which I concurred when he and I
discussed it three or four years ago. He asked whether he is
doing the right thing. And I asked a twofold question that
was very similar. Did I do the right thing when I encouraged
him to try the second-year course he proposed? And, am I
doing the right thing in my own college-level general
chemistry course?
These questions arise because every year a few
students return for Thanksgiving break and tell this teacher that
although they left high school liking chemistry and even
planning to major in it, they have been turned off by their
college course. They found the content of their high school
course interesting and relevant, it was stimulating to work
in groups on real-world problems, and this teacher made it
fun to do chemistry. Apparently their college courses did not.
Is it unfair to such students to turn them on to chemistry
when a teacher knows that they may encounter something
much less stimulating and interesting in college? Should there
be a truth-in-advertising rule for high school teachers--tell
it like it's going to be in college? Are we doing the right
thing at the college level?
For about as long as I can remember (which is
getting to be a very long time) the content of the first-year
college course has been very similar to what is covered in many
high school chemistry and AP chemistry courses. When
students take college chemistry, they often are bored because we
are teaching the same chemistry they had in high school. Or
they have a false sense of security, thinking they have
already learned everything in the college syllabus and
developing poor study habits, only to discover at some point during
the first semester that their college course has a different
pace and different expectations regarding the depth of
understanding required. The worst case is those who have
been taught the material before but lack thorough
understanding and do not have good study skills and problem-solving
skills. These students are often turned off because they are
both bored and doing poorly in the college course.
For the past five years I have been teaching a
special section of our general chemistry course that caters to the
few students who have had no high school chemistry, or who
took it some years before and remember very little. Such
students, however, constitute only 10–20% of the class, which
means that I am constantly concerned about problems of
boredom and a false sense of security among the other 80–90%.
Although data that we collected when we started this
practice implied that putting both groups in the same class was
successfully dealing with their different needs, as time goes
on it seems to be less and less successful. I am asking
myself more and more often whether I am doing the right thing.
And not just with respect to placement of students into the
course. Both content and pedagogy are open to the same question.
Shouldn't we be including more of the newest, most
exciting chemistry in what we teach? Isn't it useful for
students to know much more than we normally say about the
importance of chemistry in the economy and the applications
of chemistry in the real world? Shouldn't we be including a
balanced picture of chemistry by including areas such as
organic polymers and biochemistry that are often balkanized
into courses only selected students will take later in their
careers? Shouldn't we be experimenting with pedagogy
and evaluating its impact on students ability to recall and
use chemical concepts and facts long after our courses are
over? Are we collectively doing the right thing?
A year and a half ago I described to a group of
elementary and middle school teachers who were attending
ICE summer workshops our then-new systemic curriculum
initiative, the New Traditions project, and the other
similar NSF-funded projects. Common to all of these is new
content and pedagogy of the sort I have just alluded to. At that
time I suggested to the workshop participants that those of
us teaching in colleges and universities had a lot
to learn from teachers like themselves about
better ways to help students learn chemistry and
science in general. I continue to believe that
that is true. We need to examine, collectively and cooperatively, the questions I have
raised and many others, because we all have a lot to learn from
each other. And because there is a lot to be gained by our
cooperation and collaborationespecially by our students.
For example, those of us teaching college general
chemistry continually complain about having too much
material to teach and not enough time to do it justice. But, as
noted above, much of that material is also included in the
high school course. We argue that students have not learned
it thoroughly enough or at sufficient depth, and so it must
be done again. But we seldom communicate with high
school teachers about this issue to try to arrive at a way we
could cooperate to solve the problem. Maybe we could agree to
do certain topics only oncein the high school or the
college course, but not boththereby leaving room in both
courses for new and exciting content or pedagogy that will grab
students' interest and maintain it. Maybe this would help us
to alleviate the boredom that seems to be turning students
off at the introductory college level.
There are many more ways in which
communication, cooperation, and collaboration among high school and
college teachers would serve our students and our discipline. If
we do not actively explore them, are we doing the right thing?
